Abstract

A method for user equipment-anticipated common beam switching includes receiving, by a user equipment (UE), a set of reference signals from a network controller; sending, by the UE, a measurement report to the network controller based on a first reference signal of the received reference signals; determining, by the UE, that a quantity of the first reference signal reported in the measurement report exceeds a threshold; and based thereon monitoring, by the UE, a physical downlink control channel (PDCCH) over a search space on a first control resource set (CORESET),a spatial quasi-colocation (QCL) field in a transmission configuration indication (TCI) state of the first CORESET being set to a resource index of the first reference signal.
